" Application filedbctober 24, 1922. Serial No, 596,681.

vention being to provide an improved burner for cracking of thisclass embodying means 7 the liquid hydrocarbon and to effect con in accordance with my invention.

plete combustion thereof and thereby e'iiect' an economy in the use of the liquid hydrocarbon and also. increase the illuminating power of the burner. i With the above and other objects in view,

the invention consists'in the construction,

combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a vertical central sectional view of a lamp burner constructed and arranged Figure2 is a detail view, partly in elevation and partly in section of the cracking and difiusion plates and their supporting rod and adjustin means.

, 2, one of unequal diameter,

- call end of a vertical supporting mounted on a base or gallery 4? and in the In the embodiment of my invention, I provide a pair of tubular wick tubes 1 and which are arranged one within the other and concentrithereto to rovide space for the tubular wic which is o the usual form. The inner wick tube forms a conduit for air. cavo-convex crackin plate 2 is arranged above the u per on of the wick, with its concave side owermost' and is provided with an opening, as shown, for the passage of air therethrough and also for the passage of disassociated hydrocarbons. tance above the cracking plate 2 is a concavoconvex difiusion plate 3 which is also arranged with its concave side lowermost. Sai difiusion plate is secured at the upper rod 6 and said plate is adjustably secured on the u per, t readed portion of said rod by means 0 nuts 7 so that the cracking plate may be arranged at any required distance from and below the difiusion plate.

A chimney 4 of any suitable form is.

crackin lower endof the chimney is arranged a substantially truncated conical dia hragm 5 for the regulation of the air of com ustion A conone hand, and

A suitable diswith its concave which passes up around the outer wick tube. l "lhc operation is as follows. When the wick is-lighted a flame is generated which heats the cracking plate'2 and 'causes a draft of air up through the chimney and also up through the interior wick tube as indicated by the arrows in Figure 1.

A part of the air introduces itseli' by the exterior of the center of the wick and mixes with the dissociation resulting from thevapors of heating of the plate of cracking (primary air of the mixture/as in the ordinary Bunsen-burner) An additional part of air enters thereu on I through the space exlsting between the p ate of diffusion 3 and the diaphragm 5, this complementary 'air being necessary for the complete combustion of the dissociated hydrocarbons and for, the oxidation of the carbon, as in the ordinary Bunsen-burner.

Thereby a flame is produced, identical with that of a "Bunsen-burner and comprismg: a v

1. An obscure-center at a,

2'. A blue, pale. shell at b, and

3. A very hot and very oxiding violet color, at c.

4. A' base of the flame ate, the ed part.

In the same way,

point, of least heatas in a bunsen, it is of my improved burner necessary to regulate the proportions of air and of gas. It is also necessary to re ate the quantity of the air mixing wit hydrocarbons dissociated upon the .plate of cracking. For this purpose the distance existing between the diffusion plate the cracking plate 2 on the other, may be increased or reduced by appropriately adjusting the nuts 7 on the rod 6, as will be understood.

In order to secure the heating of the cracking plate to the required constant temperathe 3 on the tore, this plate is maintained a suitable distance from the wick, so that the flame con:

at the required'temperature during eration of the device. i

What I'claim, is:. v

' 1. A hydrocarbon burner com rising inner and outer wick tubes, a tubu ar wick arranged between the wick tubes, the said inner wick tube being also a conduit for air,

a concavo-convex cracking plate arranged side lowermost and above tinues to maintain equally the crackinfiplate 4 plate arranged with its concave side lowermost and above and in spaced relation to the cracking plate and providing a mixing chamber therebetween.

2. A hydrocarbon burner comprising inner and outer wick tubes, a tubular wick arranged between the wick tubes, the said inner wick tube being also a conduit for air, a cavo-convex cracking plate arranged witl its concave side lowermost and above and heated by the flame of the wick to disassociate. the hydrocarburets and provided with an opening therethrough for the pa'ssage of air and such disassociated hydrocarburets, and a concavo-convex diffuser plate arranged with its concave side lowermost and above and in spaced relation to the cracking plate and" providing a mixing chamber therebetween, a chimney around and in spaced relationto the cracking plate and difi'user, means to admit air to the lower end of said chimney and a diaphragm in the base of the chimney, open at its lower and upper ends and presenting an upwardly and inwardly, inclined converging wall around and in spaced relation to the cracking plate and difiuser to supply complementary air to the mixture.

3. A hydrocarbon burner comprising inner and outer wick tubes, a tubular wick arranged between the wick tubes," the said inner wick tube being also a conduit for air, a cracking plate arranged above and heated by the flame of the wick to disassociate the hydrocarburets and provided with an open-' ing therethrouglr for the passage of air and such disassociated hydrocarburets, and a diffuser plate arranged above and in spaced relation to the crackin plate and providing a mixing chamber tfierebetween, supporting means fpr the cracking plate and diffuser and including means to permit the relative adjustment of the cracking plate and diffuser towards and (from each other to vary the width of the space between them as required.

In witness whereof I afiix my signature.
